A fire retardant molding contains a thermoplastic compound and an inorganic flameproof agent that is mixed with the thermoplastic compound and which acts by separating from water, having a proportion in the range of 10 wt % to 90 wt %. The fire retardant molding is produced by mixing the thermoplastic material with an inorganic flame-proofing agent, the flame-proofing agent having a proportion in the range of 20 wt % to 80 wt %, and by outputting the compound obtained by mixing, in particular as a flat product. The fire retardant molding is advantageously used, for example, in or on land-based vehicles, water-based vehicles, aircraft and buildings.

An aqueous dispersion of graphene oxide is prepared in an additive process by subjecting graphitic carbon, such as biochar, in water or an aqueous solution to a high-shear environment in the presence of a dispersing agent to exfoliate graphene oxide. An intercalating agent may be added to facilitate exfoliation, and optionally neutralized. The graphitic carbon may be pre-processed by wet milling prior to exfoliation. The aqueous dispersion of graphene oxide may be used as a concrete admixture in a concrete composition.
